3M 7010363157 Flap Disc 36 Grit Type 29 7 Inch Zirconia

Product Description

The 3M 7010363157 is a Type 29 zirconia alumina flap disc designed for aggressive material removal on steel and stainless steel surfaces. With a 36-grit very coarse abrasive and a polyester cloth backing rated YF weight, this disc delivers consistent cut rate and durability under demanding grinding conditions. The conical Type 29 profile maintains a low grinding angle that increases surface contact and cutting efficiency on flat and contoured workpieces. Rated to 8,600 RPM, it mounts via a 5/8-11 threaded arbor hole for fast spindle changes on standard angle grinders. Fabricators, welders, and metal finishing trades rely on this disc for weld blending, surface prep, and stock removal applications.

This flap disc is suited for use on structural steel, sheet metal, and stainless steel in fabrication shops, manufacturing environments, and field metalwork. The 7-inch diameter makes it compatible with large-diameter angle grinders commonly used for heavy material removal. The zirconia alumina abrasive self-sharpens during use, extending disc life compared to standard aluminum oxide options, and the green polyester cloth backer resists heat and flexing during extended grinding passes.

Key Features

Compatibility

Designed for use on standard angle grinders with a 7-inch disc capacity and a 5/8-11 threaded spindle. Suitable for grinding and surface preparation on steels and stainless steel as stated by the manufacturer.

Installation Notes

Installation and disc changes must be performed by qualified personnel with the grinder powered off and unplugged. Verify that the grinder spindle speed rating meets or exceeds the disc maximum RPM before mounting. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Always use appropriate personal protective equipment including eye protection and gloves when operating angle grinders.
